Spice-style junction diode model for bipolar transistors
The Spice-style junction diode for BJTs is a regular diode without
heat generation. A separate model was needed to implement the
Level parameter, as the Ebers-Moll model doesn't recognize
the Area parameter. A heat port was still needed, as the
model makes use of the device temperature that it imports through
the heat port. However, the heat flow itself is zero, as the model
is used only as a mathematical construct to compute the currents of
the non-linear current sources. The heat generation is accounted
for in the non-linear sources.
Parameters:
IS: Transport saturation current (default value = 1e-16 Amp)
EG: Energy gap for temperature effect on saturation current (default value = 1.11 Volt)
N: Current emission coefficient (default value = 1)
XTI: Saturation current temperature exponent (default value = 3)
Area: Relative area occupied by the diode (default value = 1)
Level: Transistor modeling level (Ebers-Moll = 1; Gummel-Poon = 2) (default = 2)
EMin: if x < EMin, the exp(x) function is linearized (default value = -100)
EMax: if x > EMax, the exp(x) function is linearized (default value = 40)
